GRAPHENE FROM THE BEST GRAPHITE IN THE WORLD

Graphene Oxides (GO)

Graphene oxide (GO) is a single-atomic layered material, made by the powerful oxidation of graphite, a cheap and abundant raw material. Graphene oxide is an oxidized form of graphene, with various functional groups containing oxygen, such as epoxide, carbonyl, carboxyl and hydroxyl groups.

Ceylon Graphene Technologies (pvt) Ltd (CGTL) was established in June 2018, as a joint venture of LOLC Group and SLINTEC. CGTL aims to create a US$ 1.5 billion graphene-based industry in Sri Lanka and position itself among the world’s top five graphene manufacturers by 2025.

Reduced Graphene Oxides (rGO)

GO has many exciting properties like mechanical strength, thermal and electrical conductivity, intriguing optical properties and much more. Reduced graphene oxide (rGO), made by removing the oxidized functional groups from Graphene oxide (GO), is suitable for the same sorts of applications as graphene such as energy storage, composite materials, flexible electronics, chemical sensors and more.

Expanded graphites (EG)

Expanded graphite (EG) is obtained by the exfoliation of natural vein graphite. It gets its name from the fact that it expands by up to hundreds of times along the “C” axis, resulting in a puffed-up material with a low density and a high temperature resistance. Expanded graphite is used in applications that include fire retardants, high performance gaskets, conductive fillers, electromagnetic pulse and radiation shielding. It is also used as an adsorbent for gas chromatography and as a substrate for the study of adsorbed films.
